Fedora 40: FEDORA-2024-129d8ca6fc High: IceCat Type Confusion Fixes

fedora
Calendar Grey March 7, 2024
Dist Fedora Esm H88
The latest IceCat release features an overhaul of the JDK along with essential corrections addressing vulnerabilities linked to type confusion in Fedora 40.
Change for system JDK from 17 to 21

Summary

GNU IceCat is the GNU version of the Firefox ESR browser.

Extensions included to this version of IceCat:

* LibreJS

GNU LibreJS aims to address the JavaScript problem described in the article

"The JavaScript Trap" of Richard Stallman.

* JShelter: Mitigates potential threats from JavaScript, including fingerprinting,

tracking, and data collection. Slightly modifies the results of API calls,

differently on different domains, so that the cross-site fingerprint is not

stable. Applies security counter-measures that are likely not to break web pages.

Allows fine-grained control over the restrictions and counter-measures applied

to each domain.

* A set of companion extensions for LibreJS by Nathan Nichols

are pre-installed, and provide workarounds to use some services at USPS,

RSF.org, SumOfUs.org, pay.gov, McDonalds, goteo.org and Google Docs

without using nonfree JavaScript.

* A series of configuration changes and tweaks were applied to ensure that

IceCat does not initiate network connections that the user has not explicitly

requested. This implies not downloading feeds, updates, blacklists or any

other similar data needed during startup.
